监控zabbix使用jmx监控tomcat

1.在zabix服务端安装java工具(服务器已安装zabbix)

[root@db02 ~]# rpm -ivh
http://repo.zabbix.com/zabbix/2.4/rhel/6/x86_64/zabbix-java-gateway-2.4.7-1.el6.x86_64.rpm

[root@db02 ~]# vim /etc/zabbix/zabbix_server.conf
JavaGateway=127.0.0.1
JavaGatewayPort=10055
StartJavaPollers=5
[root@db02 ~]# vim /etc/zabbix/zabbix_java_gateway.conf

LISTEN_IP="0.0.0.0"
LISTEN_PORT=10055
START_POLLERS=5

[root@db02 ~]# /etc/init.d/zabbix-server restart
Shutting down Zabbix server:          [  OK  ]
Starting Zabbix server:                     [  OK  ]
[root@db02 ~]# /etc/init.d/zabbix-java-gateway restart
Shutting down zabbix java gateway:      [  OK  ]
Starting zabbix java gateway:                 [  OK  ]

[root@db02 ~]# netstat -antulp | grep 10055
tcp        0      0 :::10055                    :::*                        LISTEN      15958/java          
[root@db02 ~]#

2.在tomcat端添加一个端口,供zabbix获取数据

jmxcmd下载地址:

https://sourceforge.net/projects/jmxcmd/files/latest/download?source=typ_redirect

[root@web02 ~]# vim /usr/local/tomcat-7.0.67/bin/catalina.sh     --添加以下行,获取tomcat服务器的IP地址
CATALINA_OPTS="-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=本机IP地址"

[root@web02 ~]# vim /usr/local/tomcat-7.0.67Html/conf/server.xml      --暴露一个端口给zabbix获取数据
  <Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener"  rmiRegistryPortPlatform="9999" rmiServerPortPlatform="9999"/>
[root@web02 ~]# /usr/local/tomcat-7.0.67/bin/shutdown.sh      --关闭tomcat服务
[root@web02 ~]# /usr/local/tomcat-7.0.67/bin/startup.sh          --启动tomcat服务

[root@web02 ~]# netstat -antulp | grep 9999
tcp        0      0 :::9999            :::*                 LISTEN      12469/java              
[root@web02 ~]# java -jar jmxcmd.jar - localhost:9999 java.lang:type=Memory NonHeapMemoryUsage
04/26/2016 16:21:38 +0800 de.layereight.jmxcmd.Client NonHeapMemoryUsage:
committed: 136183808
init: 134676480
max: 318767104
used: 36691992
[root@web02 ~]#

3.在zabbix中添加分类,项目,键

(1).启用jmx模块

(2).创建分类

错误处理:

[root@web02 ~]# java -jar jmxcmd.jar  - 180.178.55.82:9999 java.lang:type=Memory NonHeapMemoryUsage

Exception in thread "main" java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.NameNotFoundException: jmxrmi

at javax.management.remote.rmi.RMIConnector.connect(RMIConnector.java:286)

解决方法:

是tomcat_java的端口被占用了
